I 63 Claims. 1

This invention pertains 'to looms `adapted to function with stationary filling supplies an'd`more specifically, to shuttleless looms of 'that 'type wherein the 'lling from .the stationar'yisupplies isA introduced into 'a warp shed by carriers at the ends of flexible members such as. tapes.

v vIt is a' general object of the invention to improve looms functioning from stationary supplies of iillincr and to improve upon a method. of oper'- ation and mechanism of such looms ofthe 'general type known as shuttleless looms.

it is a furtherobject ofthe invention to simplify looms of tlie'typel described landto render them more useful in weaving a great'ervariety of materials and to decrease the .cost of productionof thel fabric by speeding `up .the operation of the loomsv while,` at the Sametime, "less'en'ing' the possibility of imperfectionsA in the product .due to failure in inserting the weft'properly.

It is another object to rendcrthe'entire weaving-mechanism" of looms of" thisr type' more dependable and to obvi'ate 'possibilities' ofany' great percentage'loss in efficiency or Vof'imperiect .fabric due ,to uncertain action of the mechanism in .introducing the fillingto 'the'.inserting means or iin transferring the'lling from one 'insertinglmea'n's toanother and continuing its'layin'g the shed.

it is a further obj ectfof the invention to simplfy the entire mechanism and to provide. for producing selvagesof ysatisfactory itype Without" the' .addition vof any supplementarymechanism expressly for'the purpose-` Another object is that of improvinglo'oms func'- tioning from stationary filling Asupplies which', 'if iilling breaks'y between the 'filling' motion and fabric, will automatically andimmedia'telypick up the lling upon thenextpickafterbreakage' andcontinueto weave ina normal manner:

1t is a 'further landv more specifici object of" the inventionV to simplify andjtorender Amore effective filling motions for llooms vfunctioning''fromstationary filling supplies.

Another object ifs/that of devising a' new method of filling handling, that isI a'newandimprove'd system of introducing -th'e'filling to the carriersof the filling inserting mechanism, and also` aV new' method of transferring the iillingfrorn onelcarrier to another intermediate*theendsofl the s'h'ed into which the lling'is laid. Y

, It isa further object ofthe invention to devise more effective carriers' for 'the Afilling inserting means to the end that theyslia'llbe' simplerand more positive in performing 1theirintended'uhction.Y

n ruft-aerobica isthat of improvingftnedriven 2. means for the iiexible'v members and the control ofthe flexible members' themselvesv so asto speed up the operation of thev mechanism without 1intr'oducin'g complications, and further 'to avoid ,uncertain control byV improving 'the guiding of the i'iexible members themselves;

'It is a further object to improve the lay motion for the loom and to'provide for effectively beating the 4filling into -the'tfabric' AWhile* permitting' "the lay to `remain stationary throughouta suflioi'ent period of time during thecyclel'for'the fil-lingto be inserted and vforV the iilling'in'serting mechanism to be Withdrawn from'theshed.

Other objects of the invention-W ``-beco`me 'aj-pe parent fromfth'efollowingdisclosura f Loomsnavefbeendevisedf heretofore' which the .filling -issupplied from stationarysourcesand include various types oi needle ilo'oms'and' also a number: of tapellooms For Sthemostparlt, these looms have either functioned to -Weaveaspecial types of fabrics su-chxas narrow:fabrics;.or"V l..ftney have 'been' employed' ato' weave' wider ory femore standard types offabrics* suchfas are' wovennon conventional iiy- .Shuttlefloomsi they have functioned v,slowly .and l-vvigth Vvery zrnediocre gresi'lts.

These filling motions function to present the filling to the tape heads first in one particular relationship, and then in a different relationship since itisalwaysdesired to .maintain the socalled loose ,fendV or Ycut end o f the filling at the lower side of the tape mechanism so that it is controlled and more safely handled than would otherwise be the case.

It is to be understood that the mechanism, although useful for weaving a relatively great number of dierent typesof fabrics insofar as the particular physical structure or sequence of the inserted picks of filling is concerned, is primarily adapted to introduce the weft or filling in the form of U-shaped or connected pairs of picks, the single picks of which may be inserted from one side and in adjacent warp sheds, or may skip one or more sheds which are occupied by picks inserted from-the opposite side of the fabric. These U-shaped, or' connected picks of weft are sometimes referred to as hairpns, andwill be so designated in this-disclosure. The invention will be-described hereinafter in greater detail by reference to one specific embodiment thereof .andcertain modifications as evident in the accompanying-figures of drawing wherein like parts` are indicatedy by similar numeralsand wherein; l v

Now referring,v to Figs. 1, 2 and 3, the invention has been applied to a loom, many of the parts of which are of more or less` conventional design and it is to be understood that thoseparts of the loom may be Vof any desired construction since theyhave no particular connection to the tapes, the tape drives, -or tov the lay andthe filling motions which function incooperation therewith. The end frames and 1| of somewhat standard construction have been modified only insofar asis necessary to Ysupport, the different structures incidental ,to the invention, and these end frames are separated by the usual cross girts such as the front, bottom girt 12. As shown in Fig. 2, a Warp beam generally designated by numeral 13 carries a supply of warp threads 14 which are drawn from that beam and pass over a whip roll 15 which is specially controlled as will hereinafter be described.

The warp beam may be rotated or maybe permitted to rotate by any convenient let off motion (not shown).

After passing over the whip roll,` the, warp threads are threaded through a conventional stop motion generally designatedv by numeral Y16 and then through heddles 11 in harness frames; 18, these frames herein numbering only two, although it is possible to employ any convenient number such as might `be usedin a single shuttle loom. The frames are connected through the conventional hooks and harness straps running over sheaves 19 and 88 on the arch, and are drawn upwardly by springs (not shown)- but enclosed in housing 8|. Positive movement -is imparted to the heddleassemblies byvgthe usual cams, `,treadles and appurtenant harness parts, these all being of standard construction and not necessary of further description at this point.

After being threaded throughthe--heddlea the war-p threads pass through a reed 82 secured in the lay beam B3 and handrail 84, Figs. 5 and 5a. The fabric formed after insertion of thefilling and beating it into the shed is drawn toward the front of the loom tobetaken up by the usual' mechanism including a friction or sand roll positioned just behind the'breast beam 85, and

is-then wound on a fabric roll., A roll "of fabricbraced to the loomside at its upper end througha tie rod 89. A motor platform .9B is. connected at its forward end to the bracket B8 and issup-V ported at its rearmost end by a second bracket 9| which is in turn 'connected to the loomside.

as shown. A-motor 92of-specified type. is attached to the motor platform 9|)y and. through certain .interconnected .gearing venclosed within 6. the ycasing 92', drives the various parts .of the loom mechanism. 1 f

A generally rectangular supporting casting-or bracket 93 extends outwardly from the loomside and has a vertical portion indicated by numeral 94 which extends downwardly and connects to or is supported by a curved Aconnector 95 fixed to the lower end of the vertical portion Shi and attached at the rinner side of the bracket 88. At its vvinner end, this 4casting $33v vis adjustably attached to a slide 91, Fig. l, bolted to the loomsideand angularly positioned so as to be perpendicular to a plane through the tape wheel, later to be described. It is to be understood that all ofthe braces and supporting mechanism for the motor and for the tape wheel and tape supporting structures are provided lfor a ldefinite range of adjustment so that the parts may be properly positioned and may function vin proper relationship to other cooperating elements in the loom.

A horizontally disposed brace 98 is attached at its inner end to the loomside 'and is forked at its outer end, one fork end S9 being connected adjacent the upper end of the vertical portion 94 Vof rectangular bracket 93 while the lower fork portion It!) connects to a point more nearly lat the lower end of that particular element and just above the upper end of the curved connector95. The bracket 93 serves to support the tape wheel at the right hand side of the machine and also the tape guiding mechanism adjacent thereto.

Now referring to Fig. 3, the opposite tape wheel and tape guiding members are supported bymeans,l very similar to that described with respect to Fig. 2. The left hand side'of the loom is simpler in that there is no need for supporting the motor, clutch, gearing and other parts which are preferably to befound at the right hand side. At the left hand side the support for the vtape wheel and tape guiding means is evident in a bracket IGI, similar to the bracket 93 at the opposite side, and which is maintained in position'by an adjustable, sliding attachment to an inclined guide |02 bolted to the loomside 1|, and a horizontal brace m3 similar to the brace 98vat the other side, and `in addition thereto,'a more or Yless vertically disposed brace |04. This brace IM is somewhat similar to brace 88, but is not so vheavy nor is it quite as complicated since it serves no other purpose than to strengthen the support forv the parts held on lbracket 10|.

Now referring to Figs. 1, 2, 3 and 5 7, a cam shaft |05 is supported rin suitable bearings in the loomsides and carries adjacent the inner face of each loomside a pair of cams designated by numerals |08 and |01. These cams, better shown in Figs. 5 7, and which will be described injgreater detail hereinafter, are fixed tothe cam shaft to rotate therewith and serve to impart the necessary movement tothe lay, reed, etc. The cam shaft itself is driven through a clutch and gearing from the motor 92,y that motor lhaving onits rotating shaft a pinion (not shown) which meshes with the gear |08, Fig. 1, and whichis connected through to the cam shaft itself by a clutch. The clutch (not shown). is of conventional construction and similar to that commonly employed in looms and is controlled through a clutchshifter arm |09. V

.The actual control for stopping.I and star-ting the machine is derivedv from certain hand levers designated by numeralsv U0 @and -I 011e, at` each.

end Vof ythe machine. These levers are fixed at the ends of a shaft I I2 rotatable in bearings adjacent each of its ends. The right hand endof the shaft 2 has anarm ||3 fixed thereto to the free end of which is connected a depending link H4 attached at its lower end to one arm of a bell crank lever ||5. This lever ||5 is pivoted at the loomside '|0 and connects through a link ||6 attached to the other arm of lever ||5 to the clutch shifter |09 so that whenever either of the hand levers I |0 or I is moved in the appropriate direction, the clutch may be engaged or disengaged as desired. Y

A depending arm fixed adjacent the left hand end of shaft I I2 Vstrikes a contact member through which the warp stop motion may be deenergized as thev machine is stopped. Upon starting the machine again, the circuit for the warp stop motion will automatically be completed and thus, the stop motion itself will automatically be connected Within its circuit or disconnected as the machine is stopped and started.

While it forms no part of the present invention, a constant tension warp let-off is preferably employed, and the essential control parts therefor are illustrated in Fig. 3. The pivot for the whip roll is shown at I I8 and adjustably attached to that pivot is an arm ||9 to the free end of which is connected a pivot |20 for the upper end of link or rod |2| which extends downwardly to attach at |22 to one arm |23 of a two-arm lever pivoted at |24 to the loomside. Arm |23 extends to a point slightly beyond the pivot |22 and carries a freely rotatable cam follower |25 engageable with a cam |26 fixed to a vshaft |2'| on which is also fixedly mounted a gear |28. Gear |28 meshes with a pinion |29 fixed to the main cam shaft |05. y The motion derived from movement of the arm |23 as influenced by the cam |26 is conveyed through the other arm |30 of the lever to a let-off mechanism of any convenient type, that particular part of the device not being ,necessary of further description here. 'Ihe general tendency' of the warp sheet under tension is to maintain the follower |25 in contact with the cam against the tension of a spring |3| compressed between ystop collars |32 on rod |2| and an abutment |33 which -is fixed to the loomside or to any other convenient xed support. As tension increases -in the warp sheet, the whip roll is ldrawn downwardly thereby compressing spring 3| so that the cam |26 will, upon each revolution of the cam shaft, Contact vthe follower |25 and through the arms |23 and |30, will become effective to impart a greater or lesser movement to the let-off in accordance with the tension in the warp sheet. As tension is relieved, the opposite takes place and the action of the let-off becomes substantially less, or possibly, there will be no movement thereof until a vsatisfactory tension condition has been reestablished. Normally the spring |3| is maintained under such tension that practically the same amount of letoff movement is imparted as the follower |25 is contacted by a small part of the periphery ofA cam |26 upon each rotation of the cam shaft.

Now referring to Figs. 1, 2, 3, 8, 9 and 9a, at eitherv end of therfront portion of the `loom frame are supported filling motions generally indicated by numerals |34 at the right hand side of the machine and |35 at the left. These filling motions are mounted on pads machined on the ends of the breast beam'85 just above those points at which the breast beam is bolted to the front, top portion of the loomsides.- These filling motions which are to be described in greater detail in later paragraphs are enclosed within suitable casings and are to a great extent, selfcontained or unitary in that they may be bodily removed and replaced and that each is driven through its own drive means directly from the main cam shaft.

Referring to Figs. 8 and 9, a filling motion, that illustrated in these figures being the one at the .left hand side of the machine, although they are substantially identical except for the fact that they are fabricated as rights and lefts, comprises as a lower support member, the casing |36 to which is attached arcover |31 and, within certain bearings |38 and |39 at the ends of the casing, Va freely rotatable shaft upon which are mounted certain cams hereinafter to be described in detail. Shaft |39, hereinafter referred to as a filling motion cam shaft, also has fixedly connected thereto a bevel gear |40 with which meshes a bevel pinion |4| fixed to the upper, forward end of a downwardly inclined drive shaft |42. This drive shaft |42 is suitably borne Within the interior space between the loomsidesl and is driven at its lower end through spiral gearing one of which is fixed at that end of the shaft |42 and the other of which is rotatable with the main cam shaft. This gear drive from the main cam shaft is duplicated at each end and thus, each of the filling motions is simultaneously driven in synchronism with the other functioning parts'of the machine. These gears are shown in detail in Fig. 9a, the spiral gear |43 being attached to the end of shaft |42 and driven from a corresponding gear |44 keyed or otherwise fixed to the main cam shaft |05. Y

As shown in Fig. 3, the fabric take up is also driven from themain cam shaft through a gear |45 meshing with the pinion|29 and spiral gears |46 and |41, the latter being fixed at one end of a shaft |48 which ru'nshforwardly to a point adjacent the take up'gearing which is driven thereby through a worm |49 and worm wheel |50. The Worm wheel |50 vis fixedl to a short shaft which extends through the loomside and from which the conventional gears employed to advance the take up receive their movement'.

At each end of the machine the filling supply which may take the form of any of the wellknown self-sustaining thread packages, one of which is indicated by the numeral |5| is carried in a holder generallyindicated by numeral |52` supported on a post 53 which is in turn fixed to some convenient, adjacent part of the machine. The filling is drawn through a tube |55 extending from Vthe holder to the adjacent filling motion. There are preferably twofilling'supplies |5| in each holder; i These filling supplies are interconnected by tyingtogether the tail end of the package from which filling is being drawn 'with leading end tov be drawn off from the accompanying package so that when the first supply is exhausted, the loom will continue to'weave since it may immediately draw from the-second supply. Since each of the fillingsupplies is Vextremely large as compared to the ordinary shuttle bobbin utilized in fly shuttle looms, a relatively great period of time elapses between the initial introduction of filling from a fresh source and the exhaustion of filling from that source, and, since there are two, at least, of the sources available at each end of the machine, the necessity for replacing a filling package comes only at extreme intervals as'compared to the necessity of frequent replenishment in conventional loom batteries.

The amount ofwheel. A spring |85 extends about the attened part of the wheel and has a vcurved end |85 which causes the tape to conform tothe curvature of the wheel after it has left the iiattened part thereof. For holding and locking the elements in place, an angular locking clamp |81 having an opening therein to pass over the outer or short end of stud|83 is clamped in position by cap screws |88 or other equivalentI locking means. Y

The tape is maintained in contact with the rim of the wheel |60 as illustrated in Fig. 3 and more especially at the detail view of Fig. 20, by a plurality of rollers or the like herein more specifically characterized as antifriction bearings |89. These particular antifriction bearings are of the type known as permanently lubricated and sealed ball bearings, but it is to be understood that others may be substituted therefor. Each of the yguiding bearings |89 is retained within a pocket |90 formed as an integral part of a cover or guard member |9| which is maintained in position to guide and to protect the tape and tape wheel mechanism. It also serves the purpose of protecting those adjacent the loom from contact with the rapidly reciprocating elements or from possible injury in the event a tape should break. The cover .I9| may be secured in place in any satisfactory manner, but is preferably attached at the forward endof the stud |58, Fig. 2, and itis togbe understood that that stud is shouldered or is provided with suitable spacer elements so that when the cover is clamped into position, the tape wheel and its rotating gear |6| will be left with appropriate clearance for a proper running or Working fit between the adjacent parts. Y

Each of the rollers or bearings |89 is mounted on an eccentric stud |92 which constitutes one end of a threaded bolt |93 having a collar |94 formed as an integral part thereof and being adjustably locked yin position by a locking nut |95. There is a slight offset as illustrated between the stud |92 and the bolt |93 and the cone or internal raceof the bearing is held in place on the stud by a quick detachable snap ring |96 or other retaining means. The adjustment of the parts is such that the tape has a few thousandths of an inch clearance between the rim of the tape wheel when the outer surr face of the tape is pressed against the bearing. Proper adjustment is secured by applying a screw driver to the slot at the end of the threaded bolt |93 after loosening lock nut |95, and then tightening the nut to secure that particular adjustment permanently.

A suitable number of bearings |89 are spaced about the casing |9| and these may be increased or decreased within limits, although itis preferred that the tape be guided at fairly close points thereby to eliminate undulations or fluctuations in itspathway and to confine it to as nearly a truecircular path in its flexing movement as is possible. Depending upon the width of material to be woven and the size ofthe wheel |60, the tape may be wound throughout different extents, but preferably, the wheel is maintained as small as is conveniently possibleV having in mind the fact that the oscillation of the wheel cannotexceed something less than a complete revolution and also the fact that the tape is preferably to be exed throughout no smaller arc than is practicable. 'I'heoverall width of the machine is kept as small Aas is reasonable having these various limiting factors in mind.

After leaving'the toppof the tape wheel, the tape is guided tangentially from the surface of the wheel by a horizontally disposed guide member |91V carried upon a supporting plate |98 attached by suitablel bolts to the top machined pad surfaces |99 and 200 of the bracket |0|. As shown in Fig. 3 and also in the detail view of Fig. 12, the horizontal guide is really formed as an elongated slide 'in which a groove running along the top central portion of the guide is provided with a fibre bearing surface 20| along which slides the tape and over each edge of which are secured retaining strips 202 and 203. These lstrips and the bottom bearing member 20| may be formed of any phenolic resin or similar material, several of'which are available and which form ideal bearing surfaces without the benefit of more than a minimum amount of lubrication 'Ihe entire plate and guide mechanism is adjustable both vertically and angularly as well as transversely lof the tape by means of vertically disposed adjusting screws |91' which pass down through the plate to bear against a steel or other hardenedshim' on the rtop surface of vthe underlying part of plate V| 98. Bolts |98' draw the guide downwardly to retain it solidly in position. For adjusting the guide laterally the screws 204 and 205 are loosened whereupon the whole structure including plate |98 and guide |91 maybe moved since the bolts pass through enlarged-holes or slots. The entire tape mechanism may be moved forwardly and toward the back of the machine by sliding the bracket |0| along its supporting guide member |02. The braces |03 and |04, as previously mentioned, are attached at the loomsides and a' certain` amount of adjustability thereV is available through slots so that for any particular setting of the tape mechanisms, these braces may be clamped or bolted in proper position Vto serve as strengthening structural members without causing any distortion of the bracket |0|.l Thus the entire tape wheel and its driving and supporting means may be adjusted as a unit by varying the position of bracket |0| along inclined slide |02, and the tape guide-may be angularly varied, raised Vor lowered or set ahead or back to align the tape with its wheel and with the lay and the opposite tape.V

n Adjacent the inner end of the guide member |91 the tape is restrained so that it must conform-to a particular pathway without imposing on it any appreciable additional friction. For that purpose, at eachv edge of the tape there is provided a contact roller 206 functioning against the top of the tape and pivoted on a horizontal axis and a' similar roller 201 adapted to bear against the tape edge. Since these rollers and the mounting therefor are duplicated at each side of the tape, only those at one side have been illustrated in Fig. 12. The horizontally pivoted roller-206 is rotatable upon a bearing stud fixed in a boss 208 which forms an integral part of the inner end of the tape guide |91. While an adjustment may be provided for this roller, it has not been found necessary.

The other roller 201 which bears against the tape edge is more preferably adjustable since, by this means it is possible to cause the tapes and their attached carriers to align more accurately, thereby to facilitate entry of one within the other at the transfer atrthe center of the lay when the tapes have been extended inwardly to their fullest extent. The roller 201 is carried at the. top end of a stud 209 and that: stud is held within an. eccentrically` disposed aperture in. a sleeve 2|0 having its lowermost portion formed as an enlarged cup-shaped memberlll within which a locking nut 2|2 is threaded to the lower end of the stud 209. By loosening the. nut 2|2. and turning the sleeve 2||l by engagement o1" a suitable tool with the cup-shaped` part 2| I, the roller 201 may be brought toward or moved away from the center of the guide |91 thereby todirect the tape |80 either toward one side or 'the other of' a normal, central pathway alongl the lay. It isy to be understood that thel guides 2&2 and 263 hold the tape downwardly and that there is a certain amount of' clearance both vertically and along thev edges of the tape, the primary directional constraint therefor being derived from these rollers. When proper adjustment has been secured, the eccentric member isheld While the lock nut 2|2 is tightened.l y y Preferably the rollers 206 and 297 are therouter members of small antifriction bearings such as needle bearings,- although itis to be understood that they may be formed as plain rollers mounted on lubricated bushings. In the interest of maintaining proper lubrication'and preventing wear, and since the tape must be run as dry as is practicableV in order toA preventH soiling the threads'which form the fabric, thev self-contained and permanently lubricated bearings `of the type described are preferred. l

As illustrated in Figs. 22 and 23, the tape |80 at the left hand side of themachine has attached at its end a carrier 2 I3, this particular tape having the larger carrier attached thereto, `although it is quite possible to reverse the arrangement. yAt the opposite side of the machine as illustrated in Fig. 2, a similar tape Wheel is driven in substantially the same manner and at that side the tape is guided in correspondingl guiding elements and has attached thereto a smaller carrier numbered 2 I4. For convenience this right'- hand tape is designated by numeral 2|5 and is precisely the sameas the left hand tape, the only difference being' in the carriers themselves and the manner of attaching the carriers to the ends ofthe tapes.

Carrier r2|3 is attached by a screw 2'| 6'or other means to a block, the said screw also serving to retain other parts of the carrier later to be described.' The carrier and itsv block are then is narrower than the widthof' the tape itself' since it must pass between the` guide means for the tape'asjitA moves to outermost position.

The opposite or smaller carrier is'attached in asimilar manner exceptfor the factv that a pair of attaching screws numbered 2|? pass vertically through, the carrier and i'ntoa supporting block hothof :which are brazed to the. endv o f thetape. These carriers will' be describedtin greater detail ina later part of thelspecification whereinv the headsand 'their function. are to. be discussed morefully. f. I, I It is 'to be `understoodthat" the tape wheels areoperated' synchroiiously,so vthat each of the tapesand':itsv head is projectedinto'. .thev shed and is withdrawn therefrom atsubstantially the same time'. The heads meet'fat about'lthe v,cen-ter for accomplishing transfenjalthough itis to be; un-` derstood that; aslight` amount of Ydeviation may bey permitted, lbut in' orderV to take; 'advantage of' the maximum amcuntrnf available time forin- As shown in Fig. 3, each of the eccentric sheaves f such' as the sheaveV |'|6 has a certain amount of angular adjustment about the cam shaft |05. This adjustment is provided by certain slots in a sector 2|8 which extends outwardly from a hub 2|9 set screwed or otherwise xedly attached for rotationA with thev cam shaft. rOne or more screws 220 are threaded into the eccentric. sheave and pass through vthewslots in the sector 2|8. When proper adjustment has been effected by adjust'- ing screws 22|,one at either side of the sector,v

and which extend inwardly to contact the adjacent screw 220, the screws y22|) are tightened thereby clamping Vthe parts in properly adjusted position.

At the extreme left hand end of the cam shaft a hand wheel 222 is providedfor turning the'parts slowlyr and manually as is frequently necessary in making adjustments or in, running the loom through a cycle or more forthe purpose of observing the actual functioning of the operative parts.. j Lay and' Zal/motion Now referring to Figs.A 5, 5a',` 6 and 7, the la motion will bei described in. detail. As'previo'usly mentionedthe lay parts and reed are mountedon lay swords |56 and rock about rock shaft |51.

The actual construction. of the las,7 swords is'suchv thatA in cooperation Withthe supporting means therefor which forms a part of the rocking levers 223, the layitself may be vertically adjusted, each end thereof bei-ng capable ofV independent movement.

The swords are machined.v to have flat surfaces somewhat vertically disposed, each of which forms the face of afpad224. which is'slidably mounted upony acorresponding pad 225 on its respective lever 2213. keyv and. key slot designated by numeral,22.maintain the -parts in proper vertical alignmentI and a pair of adjusting studs having nuts 221 and 22.8` pass. through elongated slotsv in the' pad 22.43y and are held within the cooperating pad 225 to maintain the parts in any desired adjusted position.

The actual vertical positioning. of the swords and parts carried thereby is effected by lifting screws 229 threaded downwardly into the top portion of the pads 225 and having their heads bearing against a shoulder or ledge 230 cast as an integral part of the swords themselves. A locking nut 23| maintains the parts adjusted in properly elevated positionI in addition to the clamping studs and their nuts 22.1 and 228.

The levers 223 of which there are two, one at each lay sword and thus one adjacentreach end of the machine, are forked having one fork por non zal:l offsetsugh-uy towardrhe outerend of the loom so as to align with: the cam Ill@T which is at the outer end of the-.camshaft as compared to the cam |01. f This forked and offset end 232. carriesr a: follower inthe form of a rollerv 2.33 for engagement with the cam |06.; Y

The other endll of the forl designated' by. nu.- meral 234 has `a pivot 235 on which is freely oscillatable a two-armed .lever 236 to the. outer
